Abstract

The two-phonon infrared absorption spectrum of the covalent elemental semiconductors Si and Ge is calculated completely ab initio. Besides the harmonic phonon eigen solutions this involves the phonon-photon coupling constants, the so called second-order dipole moments (also called dipole coefficients). These are given by the third-order derivatives of the total energy with respect to an electric ...
